Description

Technical Field

[0001] This invention relates to refrigerated container technology, specifically to a multi-functional, integrated, energy-saving refrigerated container. Background Technology

[0002] Edible fungi refer to fungi that can be consumed. They are usually rich in nutrients such as protein, vitamins, and minerals, and are widely used in the cooking and consumption of various dishes.

[0003] In order to ensure the freshness of edible fungi during transportation, refrigerated containers are generally used for refrigerated transport. During refrigerated transport, in order to ensure that the transport vehicle and the goods inside comply with relevant regulations and standards, relevant personnel will usually inspect the goods inside the refrigerated container.

[0004] Traditionally, when inspecting cargo in refrigerated containers, the doors are opened and inspectors enter the container to conduct random checks. During this process, the cold air inside the refrigerated container directly exchanges heat with potential sources in the external environment, causing significant temperature fluctuations inside the container. This not only affects the storage of cargo inside the refrigerated container but also increases the operating power of the refrigeration unit, thus raising transportation costs. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional, integrated, energy-saving refrigerated container to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional integrated energy-saving refrigerated container, comprising a body, two doors located at the rear of the body, and a refrigeration unit located at the head of the body. Each door is equipped with a convenient inspection mechanism, which includes a first entry point on one of the doors. A transfer compartment connected to the first entry point is fixedly connected to the inner side of the door. A second entry point connected to the interior of the body is located on the side of the transfer compartment. A first sealing door corresponding to the first entry point is provided on the door. A second sealing door corresponding to the second entry point is located on the outer side of the transfer compartment. Connecting components are provided outside the first and second sealing doors, respectively, to connect the first and second sealing doors to the transfer compartment.

[0007] A locking device is provided between the first sealing door and the side door, and the locking device is used to connect and fix the first sealing door and the side door.

[0008] Furthermore, the shape and size of the first sealing door are adapted to the first entrance, and the first sealing door can be embedded inside the first entrance. The position, shape, and size of the second sealing door correspond to the second entrance, and the second sealing door can cover and seal the second entrance.

[0009] Furthermore, the connecting assembly includes a partition layer formed at the top of the transfer compartment and the top of the compartment. A fixed seat is fixedly connected to the surface of the first sealing door. A straight groove is formed on the inner side of the partition layer. The longitudinal cross-section of the straight groove is cross-shaped. A movable block adapted to the straight groove is slidably connected to the inner side of the straight groove. A movable seat is fixedly connected to the outside of the movable block. A connecting beam is rotatably connected between the fixed seat and the movable seat. When the first sealing door is embedded inside the first inlet until its outer surface is flush with the outer surface of the compartment door, the movable block moves to the end of its stroke on the side of the straight groove away from the first sealing door. When the movable block moves to the end of its stroke on the side of the straight groove close to the first sealing door, the first sealing door moves out of the first inlet.

[0010] Furthermore, positioning blocks are fixedly connected to the surfaces of the fixed seat and the movable seat respectively. The two positioning blocks are respectively set on both sides of the connecting beam. When the connecting beam rotates to the point where both sides abut against the two positioning blocks respectively, the first sealing door rotates to be parallel to the compartment door.

[0011] Furthermore, the outer side of the transfer compartment is provided with guide grooves located on the upper and lower sides of the second entrance. The inner side of the guide groove is slidably connected with a guide block, and the guide block is fixedly connected to the second sealing door. Sealing gaskets are provided on the surface of the second sealing door near the second entrance and the surface of the first sealing door near the first entrance.

[0012] Furthermore, the locking component includes a rotating seat fixedly connected to the surface of the door, a bolt rotatably connected to the outer surface of the rotating seat, an L-shaped plate fixedly connected to the outer surface of the first sealing door, an embedding groove between the L-shaped plate and the first sealing door, and the bolt rotatably embedding into the embedding groove.

[0013] Furthermore, the first and second sealing doors are equipped with locking mechanisms on their exteriors. These mechanisms include a slot on the side of the first sealing door, an auxiliary slot communicating with a guide slot inside the transfer compartment, a push block slidably connected to the inner side of the auxiliary slot on the surface of the guide block, a movable slot extending into the transfer compartment inside the compartment door, the movable slot communicating with the auxiliary slot, a push plate slidably connected to the inner side of the movable slot in the same direction as the movement of the second sealing door, one end of the push plate passing through and extending into the auxiliary slot, a locking rod slidably connected to the inner side of the movable slot in the same direction as the width of the first sealing door, a return spring fixedly connected between the locking rod and the inner wall of the movable slot, the maximum deformation rebound force of the return spring being less than the movement resistance of the second sealing door, an arc-shaped portion on the end of the locking rod near the slot, and a linkage rod rotatably connected between the push plate and the locking rod.

[0014] Furthermore, the position and size of the locking rod are adapted to the locking slot. The end of the locking rod near the locking slot can be embedded inside the locking slot. The arc-shaped surface is provided on the side of the locking rod away from the second sealing door. The linkage rod is inclined. When the push plate moves into the movable slot, the linkage rod can drive the locking rod to move away from the locking slot. When the push plate moves out of the auxiliary slot, the locking rod moves synchronously and exits from the locking slot.

[0015] Furthermore, the inner side of the transfer compartment is provided with a straight groove, and a clamping plate is slidably connected to the inner side of the straight groove. A compression spring is fixedly connected between the surface of the clamping plate and the inner wall of the straight groove. The maximum deformation rebound force of the compression spring is less than the moving resistance of the first sealing door. The interior of the transfer compartment is provided with an extension groove that communicates with the straight groove. A pull block is slidably connected to the inner side of the extension groove. A traction rope is fixedly connected to the side of the pull block and the end of the clamping plate. The inner wall of the straight groove is provided with an inner groove that communicates with the straight groove and the extension groove. The interior of the transfer compartment is provided with a wiring groove that connects the inner groove and the straight groove.

[0016] Furthermore, both ends of the traction rope pass through the inside of the wiring groove, the position of the clamping plate corresponds to the second sealing door, when the guide block moves to the end of the travel of the guide groove away from the clamping plate, the clamping plate can move and abut against the side of the second sealing door near the clamping plate, when the moving block pushes the pulling block to the end of the travel of the extension groove, the traction rope pulls the clamping plate to move and separate from the second sealing door.

[0017] Compared with existing technologies, the multifunctional integrated energy-saving refrigerated container provided by this invention has the following beneficial effects:

[0018] 1. This multi-functional integrated energy-saving refrigerated container allows for single-sided opening of the first entrance on the door, along with the coordination between the transfer compartment, the first sealing door, the second sealing door, and the second entrance, during cargo inspection. This prevents direct heat exchange between the cold air inside the refrigerated container and the outside air, significantly reducing the loss of cold air and minimizing temperature fluctuations inside the container.

[0019] 2. This multi-functional, integrated, energy-saving refrigerated container allows a small amount of cold air to enter the transit compartment during the initial opening of the second sealing door. This cools the hot air entering the transit compartment when the first sealing door is opened, ensuring that when the cooled air in the transit compartment exchanges heat with the cold air inside the container when the second sealing door is opened, it does not significantly affect the internal temperature of the refrigerated container. This is beneficial for the normal operation of refrigerated cargo.

[0020] 3. This multi-functional integrated energy-saving refrigerated container, through the use of a locking mechanism, can restrict the opening of the first and second doors during their operation, ensuring that only one door can be opened at a time, preventing simultaneous opening. This greatly reduces the direct heat exchange between the cold air inside the refrigerated container and the outside air, resulting in lower losses of cold air during inspection.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please see Figures 1-10A multi-functional integrated energy-saving refrigerated container includes a body 1, two doors 2 located at the rear of the body 1, and a refrigeration unit 3 located at the head of the body 1. The doors 2 are equipped with a convenient inspection mechanism 4, which includes a first entry 41 on one of the doors 2. A transfer compartment 42 connected to the first entry 41 is fixedly connected to the inner side of the door 2. A second entry 43 connected to the interior of the body 1 is opened on the side of the transfer compartment 42. A first sealing door 44 corresponding to the first entry 41 is provided on the door 2. A second sealing door 45 corresponding to the second entry 43 is opened on the outer side of the transfer compartment 42. A connecting component 46 is provided on the outside of the first sealing door 44 and the outside of the second sealing door 45. The connecting component 46 is used to connect the first sealing door 44 and the second sealing door 45 to the transfer compartment 42 respectively.

[0039] A locking element 5 is provided between the first sealing door 44 and the side door 2. The locking element 5 is used to connect and fix the first sealing door 44 and the side door 2.

[0040] Specifically, the shape and size of the first sealing door 44 are adapted to the first entrance 41, and the first sealing door 44 can be embedded inside the first entrance 41. The position, shape and size of the second sealing door 45 are corresponding to the second entrance 43, and the second sealing door 45 can cover and close the second entrance 43, so that the first sealing door 44 and the second sealing door 45 can respectively close the first entrance 41 and the second entrance 43.

[0041] In this embodiment, the connecting component 46 includes a partition layer formed between the top and the top of the transfer compartment 42. A fixing seat 461 is fixedly connected to the surface of the first sealing door 44. A straight groove 462 is formed on the inner side of the partition layer. The longitudinal cross-sectional shape of the straight groove 462 is cross-shaped. A moving block 463 adapted to the straight groove 462 is slidably connected to the inner side of the straight groove 462. That is, the longitudinal cross-sectional shape of the moving block 463 is consistent with that of the straight groove 462, so that the moving block 463 can only slide along the inner side of the straight groove 462 and cannot exit from its interior.

[0042] Specifically, the movable block 463 is externally fixedly connected to a movable seat 464, and a connecting beam 465 is rotatably connected between the fixed seat 461 and the movable seat 464. When the first sealing door 44 is embedded inside the first entry port 41 until its outer surface is flush with the outer surface of the door 2, the movable block 463 moves to the end of its stroke on the side of the straight groove 462 away from the first sealing door 44. When the movable block 463 moves to the end of its stroke on the side of the straight groove 462 that is far from the first sealing door 44, the first sealing door 44 moves out of the first entry port 41.

[0043] Furthermore, positioning blocks 468 are fixedly connected to the surfaces of the fixed seat 461 and the movable seat 464 respectively. The two positioning blocks 468 are respectively set on both sides of the connecting beam 465. When the connecting beam 465 rotates to abut against the two positioning blocks 468 on both sides, the first sealing door 44 rotates to be parallel to the door 2. This makes it easy to determine the angle of the first sealing door 44 when it closes the first entrance 41, so that the first sealing door 44 can be embedded into the first entrance 41 to close the first entrance 41.

[0044] Furthermore, the outer side of the transfer compartment 42 is provided with guide grooves 466 located on the upper and lower sides of the second entry 43. The inner side of the guide grooves 466 is slidably connected with guide blocks 467. The guide blocks 467 are fixedly connected to the second sealing door 45. The surface of the second sealing door 45 near the second entry 43 and the surface of the first sealing door 44 near the first entry 41 are both provided with sealing gaskets.

[0045] In this embodiment, the locking member 5 includes a rotating seat 51 fixedly connected to the surface of the door 2. A bolt 52 is rotatably connected to the outer surface of the rotating seat 51. An L-shaped plate 53 is fixedly connected to the outer surface of the first sealing door 44. An embedding groove 54 is formed between the L-shaped plate 53 and the first sealing door 44. The bolt 52 can be rotatably embedded into the embedding groove 54.

[0046] When it is necessary to inspect the cargo inside the refrigerated container, the latch 52 is rotated to disengage it from the insertion groove 54, thus unobstructing the movement of the first sealing door 44. At this time, the operator pulls the first sealing door 44 outward. After the first sealing door 44 moves out of the first inlet 41, under the transmission of the connecting beam 465, it can drive the guide block 467 to slide along the inner wall of the guide groove 466 and move to the end near the first inlet 41, moving the first sealing door 44 towards the movable seat 464. During this process, the connecting beam 465 rotates, allowing the first sealing door 44 to move away from the first inlet 41. The first entrance 41 is opened, allowing inspectors to enter the transit compartment 42. After entering, the first sealing door 44 is pushed in the opposite direction to close the first entrance 41 again. At this point, the operator can manually push the second sealing door 45 to open it, allowing them to enter the refrigerated container for cargo inspection. During this process, the single opening of the door on one side prevents the cold air inside the refrigerated container from directly exchanging heat with the air in the outside environment, thus greatly reducing the loss of cold air inside the container.

[0047] Example 2:

[0048] Please see Figures 11-12This embodiment provides a technical solution based on the above embodiments: Locking mechanisms 6 are provided on the exterior of the first sealing door 44 and the second sealing door 45. The locking mechanism 6 includes a slot 61 formed on the side of the first sealing door 44. An auxiliary groove communicating with a guide groove 466 is formed inside the transfer compartment 42. A push block 62, which is slidably connected to the inner side of the auxiliary groove, is fixedly connected to the surface of the guide block 467. A movable groove extending into the transfer compartment 42 is formed inside the compartment door 2. The movable groove is connected to the auxiliary groove. A push plate 63, which is slidably connected to the inner side of the movable groove and is arranged in the same direction as the movement direction of the second sealing door 45, is slidably connected to the inner side of the movable groove. One end of the push plate 63 passes through the auxiliary groove and extends into the auxiliary groove. A push plate 63, which is slidably connected to the inner side of the movable groove and is aligned with the width direction of the first sealing door 44, is slidably connected to the inner side of the movable groove. The locking lever 64 is fixedly connected to the inner wall of the movable groove by a return spring 65. The maximum deformation rebound force of the return spring 65 is less than the moving resistance of the second sealing door 45, which can ensure that the normal closing function of the second sealing door 45 is not affected by the return spring 65. When the second sealing door 45 and the first sealing door 44 are in the closed state, the return spring 65 cannot return to its original position. When the second sealing door 45 is opened, the second sealing door 45 no longer obstructs the return spring 65 from returning to its original position, so that the return spring 65 can push the locking lever 64 to move into the slot 61, so that the first sealing door 44 cannot be opened. The end of the locking lever 64 near the slot 61 is provided with an arc-shaped surface 66. The push plate 63 is rotatably connected to the locking lever 64 by a linkage rod 67.

[0049] Specifically, the position and size of the locking rod 64 are adapted to the locking slot 61. The end of the locking rod 64 near the locking slot 61 can be embedded inside the locking slot 61. The arc-shaped part 66 is set on the side of the locking rod 64 away from the second sealing door 45. The linkage rod 67 is inclined. When the push plate 63 moves into the movable slot, the linkage rod 67 can drive the locking rod 64 to move away from the locking slot 61. When the push plate 63 moves out of the auxiliary slot, the locking rod 64 moves synchronously and exits from the locking slot 61.

[0050] In this embodiment, a straight groove is formed on the inner side of the transfer compartment 42. A retaining plate 68 is slidably connected to the inner side of the straight groove. A compression spring 69 is fixedly connected between the surface of the retaining plate 68 and the inner wall of the straight groove. This ensures that the normal closing function of the first sealing door 44 is not affected by the compression spring 69. When the second sealing door 45 and the first sealing door 44 are both in a closed state, the compression spring 69 cannot return to its original position. When the first sealing door 44 is open, it no longer obstructs the return of the compression spring 69, allowing the compression spring 69 to push the retaining plate 68 to move outward from the straight groove. The reverse movement of the second sealing door 45 is restricted, preventing the second sealing door 45 from opening. The maximum deformation rebound force of the compression spring 69 is less than the movement resistance of the first sealing door 44. The interior of the transfer compartment 42 is provided with an extension groove that communicates with the straight groove 462. A pull block 610 is slidably connected to the inner side of the extension groove. A traction rope 611 is fixedly connected to the side of the pull block 610 and the end of the card plate 68. The inner wall of the straight groove 462 is provided with an inner groove that communicates with the straight groove 462 and the extension groove. The interior of the transfer compartment 42 is provided with a wiring groove 612 that connects the inner groove and the straight groove.

[0051] Specifically, both ends of the traction rope 611 pass through the inside of the cable tray 612. The position of the clamping plate 68 corresponds to the second sealing door 45. When the guide block 467 moves to the end of the travel of the guide tray 466 away from the clamping plate 68, the clamping plate 68 can move and abut against the side of the second sealing door 45 near the clamping plate 68. When the moving block 463 pushes the pulling block 610 to move to the end of the travel of the extension tray, the traction rope 611 pulls the clamping plate 68 to move and separate it from the second sealing door 45.

[0052] During the opening of the first sealing door 44, under the transmission of the connecting beam 465, the moving block 463 moves along with the first sealing door 44, so that the moving block 463 no longer squeezes the pull block 610. Under the action of the rebound force of the compression spring 69, the clamping plate 68 moves outward from the straight groove and abuts against the side of the second sealing door 45, thereby restricting the opening of the second sealing door 45. When the first sealing door 44 is closed, the moving block 463 moves and pushes the pull block 610 to move, so that the pull block 610 pulls one end of the traction rope 611, and its other end pulls the clamping plate 68 to move into the straight groove and separate from the second sealing door 45, so that the opening of the second sealing door 45 is no longer obstructed.

[0053] During the opening of the second sealing door 45, the movement of the second sealing door 45 drives the guide block 467 to move, and the movement of the guide block 467 drives the push block 62 to move, causing the push block 62 to separate from the top push plate 63, thus no longer restricting the movement of the top push plate 63. At this time, under the action of the return spring 65, the locking rod 64 moves into the slot 61, and under the transmission of the linkage rod 67, the locking rod 64 moves to push the end of the top push plate 63 into the auxiliary slot, so that the locking rod 64 can cooperate with the slot 61 to restrict the opening of the first sealing door 44. When the second sealing door 45 is closed, the guide block 467 and the push block 62 move synchronously with the second sealing door 45 and push the top push plate 63, so that under the push of the linkage rod 67, the locking rod 64 exits from the slot 61, thus no longer restricting the opening of the first sealing door 44.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
